Improvements of land surface elements systematic

Abstract

Systematic is considered to be the stage of methodological development in geomorphology that goes after classification. At the same time it is the first stage of systems approach in this field. Morphological system proposed by author earlier has been modified without changes of its axiomatic system and language. Forth parameter was added into its parametric form - plane curvature of land surface. Morphologically ulterior lines of maximum and minimum gradients were excluded from the set of linear elements while the ridge and keel lines within the slope relief with negative anisotropy was added. Therefore some significant corrections were made in the complete groups and in the systematic of points and area elements.
